Application filed August 14:, 1918. Serial Itoi M9367.

To all whom it may concern: 7

Be it known that 1, JAMEs S. Kmer a citizen of the United States, residing at the city and county of Denver andState of Colorado, have invented certain new and useful Improvements in Padlocks; and I do declare tion.

This invention relates to means for locking automobiles, the present device being a lock for locking the throttle against movement.

The object is the production of a small, simple locking device which will eflectually prevent operation of the engine.

Briefly, the device comprises a lock body containing a tumbler controlled cylinder of till which operates an eccentriolt. Secured to the lock body standard desi eally mounts 'is a flexible shackle adapted to be bent and inserted in a slot in the lock body, the in serted end of the shackle being held by the lock bolt. The end of the shackle is adjustable in the lock to vary the eye to fit the parts being locked. In the drawings:

Figure 1 is a front view of the lock.

Fig. 2 is a side view indicated by line Qr-2 of Fig. 1.

Fig. 3 Fig. 1.

Fig. 4 is taken substantially on the line 4-4: of Fig. 3, and shows the inner face of one half of the lock body.

Fig. 5 is taken on the line 5-5 oi Fig. 3 and shows the inner face of the other half of the lock body.

Fig. 6 is a section on the line 68 of Fig. 1. a

Fig. 7 shows the application of the lock in use.

The lock comprises a flat casing having two parts 10 and 12 through which a standard lock cylinder 13 having the usual tumblers extends. A 100 bolt 14: is eccentrically mounted on cylinder 13 through the medium of an annular groove 15 therein The bolt reciprocates in a recess 16 in the casing member 12' and has on its free end oppositely extending spring arms 17 having projections 18 thereon. a

A slot 1 9 runs across the casing member 10 is a cross section on line 3-3 of and has a pocket 20 communicating therewith in which the spring arms I? operate. A flexible, resilient, metallic shackle 21 having a series of teeth 22 on one edge thereof is secured to the member 12 and is adapted to be bent and extended through the slot 19.

As the edge of the shackle and the teeth thereon come into engagement with the beveled faces 118 of the projections 18, the latter will be forced back into the pocket 20 to permit passage of the shackle, but the spring arms 17 will urge the projections forward into engagement with the teeth, and engagement of the transverse edges of the projection 18 with those of the teeth will prevent withdrawal of the shackle. The series. of

teeth 22 also permits adjustment of the shackle to vary the size of the fitthe parts bein locked.

Turning of the ock cylinder 13 by the key A will cause the lock bolt 1% to carry the pr jections back into the pocket 2% and tree the teeth 22 of the projections 18 whereupon the shackle may be withdrawn.

In use the shackle is plmed aroimd the throttle lever B and the stationary transverse bar C on the steering wheel and the two locked together.

eye learned to The operation of the lock will be clear from the "foregoing description. Fitting the eye to the parts being locked will prevent the insertion of a tool between the shackle and I said parts for breaking the shackle.

ll claim:

1. A look casing having a slot therethrough and a flexible sheet metal shackle thereon, teeth on one edge of the shackle, the shackle being adapted to be inserted into the slot, and means in the lock to engage the teeth and retaining the shackle in locked'position.

2. A flat casing and a flexible sheet metal shackle secured flatwise to one side of said casing, a passage through said casing parallel to the flat sides thereof and of a width to receive said shackle, engaging means on one edge of said shackle, and a reciprocating member for engagement with said engaging means.

3. A flat lock casing, a flexible sheet metal shackle secured -flatwise to.one side of said casing, a passage through said casing parallel to the flat sides thereof, and of a Width to receive said shackle, engaging means on one edge of said shackle, and a reciprocating locking member, said member comprising a this bolt mounted in a recess in the casing and guided thereby, and a spring arm on one end of "said bolt having means to engage said engaging means.

4. A flat lock casing, a flexible sheet metal shackle secured fiatwise to one side of said casing, a passage through said easing parallel to the flat side thereof, and of a Width to receive said shackle, teeth on one edge of said shackle and a reciprocating locking member 1e municating with said passage and adapted to 15 engage said teeth.

In testimony whereof I afliX my signature.
